 plains of Apam. Numerous varieties are figured by 

 Segura, El Maguey, 4 ed., pi. 1-9. Vast confusion 

 exists in current literature: the names .4. americana and 

 A. mexicana are often applied to this, and it is difficult 

 to account elsewhere for the many new Latin names 

 given to pulque magueys by Blasquez, and to a number 

 of young garden plants by Jacobi. A yellow-margined 

 variety (also listed as belonging to A. mitrs'formis) is 

 var. marginata, Trel. A very large- and concave-lvd. 

 un variegated form is Var. cochlearis (.4. lalissima, 

 Jacobi. .4. lt7i(((;A:(')(', Hort.). Other important pulque 

 or agua-miel species are: about the City of Mexico, 

 A. Mapisaga, Trel. (maguey mapisaga) with narrow 

 small-prickled lvs. ; about Durango, A. compluviata, 

 Trel. (maguey verde), with green-zoned deeply gutter- 

 shaped lvs., and A. quiotifera, Trel. (maguey ceniso), 

 with ashen lvs.; about San Luis Potosi, A. gracilis- 

 pina, Engelm. (A. j/oloslna, Web.), with slender spine, 

 and A. crassispina, Trel., with stout spine; and about 

 Monterey, A. melliflua, Trel. (maguey manso), with 

 elongated ashen lvs., and A. zonata, Trel. (maguey 

 verde), with broad green-zoned lvs.
